The variable top attribute controls which characters to ignore and is only meaningful if the alternate attribute is not non-ignorable.
也可以将那些属性定义为vars(可变变量)，然后也会生成setter方法。
We could have defined those attributes as vars (mutable variables), then setters would have also been generated for us.
一些属性是可变的，但仅作为副作用(例如，当服务器启动或停止时，operationalstatus属性可能会更改)。
Some of the properties were mutable, but only as a side effect (for example, the OperationalStatus property could change when the server was started or stopped).
为此提供基本支持的属性；更复杂的方案使用可变点和对自定义组件的外部调用。
Properties that provide basic support for this; more complex scenarios use points of variability and outcalls to a customizing component.

Immutable data is a key aspect of many languages that focus on concurrency because it has such nice properties.
很多人现在都投身于函数式编程的世界，由于它们具有不可变的对象，以及与生俱来的线程安全属性。
